Start year 2012 End year 2016 Funding (€) € 911,990 Website http://randd.defra.gov.uk/Default.aspx?Menu=Menu&Module=More&Location=None&Completed=0&ProjectID=18328 Summary The benefit of this project to policy will be an improvement in the robustness of stock assessments for commercial fisheries and the ability to detect the effectiveness of real, implemented management regimes. The Management Strategy Evaluation modelling approach is critical when seeking scientific advice in relation to targets and objectives (e.g. Maximum Sustainable Yield). The outputs will be shared in the International Council for the Exploration of the Seas (ICES) crab working group (WGCRAB).
Goals:
(1) To conduct shore based intertidal surveys to locate and quantify juvenile crabs and lobsters, and to assess whether the data reflect recruitment signals for these species; (2) To conduct potting surveys using traps modified to retain undersize animals (i.e. small meshed and reduced entrance size); (3) To assess a "pre-recruit" survey, to ascertain whether valid recruitment signals are found in the data collected. The surveys will assess in-year temporal variations. Commercial pot selectivity is not wholly restricted animals above the minimum landing size and therefore the commercial fishery is also a potential source of signals of the last stage of pre-recruitment. Wild animals will be retained at sea in cages to ascertain growth rates. This method will be assessed as an alternative to the "tank captive", and "tagged and repeatedly measured" methods that have been trialled before but have significant limitations in the data they provide.
